Question

1. in the simulator, experiment by adding each type of particle to your atom. based on this, which particle determines the name of the element? protons

what element is it? - create the following atoms, then answer the questions on the right.
particles what element is it?
protons: 7
neutrons: 7
electrons: 7
protons: 7
neutrons: 8
electrons: 8
protons: 8
neutrons: 7
electrons: 7

1. did the identity of the element change when the number of neutrons and electrons was changed? no
2. did the identity of the element change when the number of protons was changed? yes
3. open the tabs titled

et charge\ and \mass number.\ now add additional protons, neutrons, and electrons to the last atom you created. which of these particles affects the mass of the atom? protons and neutrons

1. re - create a basic nitrogen atom with 7 protons, neutrons, and electrons. each of the dotted - line circles are called energy levels. are both energy levels used in an atom of nitrogen? yes
2. in a neutral atom of nitrogen, how many electrons are in the inner energy level? 2
3. in a neutral atom of nitrogen, how many electrons are in the outer energy level? 5
4. continue to add more electrons to the nitrogen atom until there are none left. what is the maximum number of electrons can be held in the outer energy level? 8
5. when additional electrons are added to a neutral atom of nitrogen, what changes? it becomes a negatively charged ion.

Explanation:

The number of protons determines the element's identity. Changing neutrons and electrons doesn't change the element (isotopes and ions respectively), but changing protons does. Protons and neutrons contribute to an atom's mass. Nitrogen has 7 electrons, with 2 in the inner - energy level and 5 in the outer one. The outer - energy level can hold a maximum of 8 electrons. Adding electrons to a neutral nitrogen atom makes it a negatively - charged ion.

Answer:

1. Protons
2. No
3. Yes
4. Protons and neutrons
5. Yes
6. 2
7. 5
8. 8
9. It becomes a negatively charged ion
